The present invention relates to a complex packing, especially adapted for the transport and storage of liquid and pasty products in large quantities, for example of the order of a thousand litres or more, this packing having a large safety factor during handling while full, while enabling a small volume to be obtained when empty. The complex packing is composed firstly of a plastic bag of parallelepiped shape capable of being folded flat when empty, and secondly of a pallet of corresponding parallelepiped shape which constitutes a rigid outer casing for the plastic bag, the pallet comprising a base platform and four dismantlable sides, of which at least two have handles for handling by slings. The platform is furthermore arranged so as to receive a cross-member which may be engaged in the handles of the pallet located immediately below, so as to couple the two pallets together for handling in series.
A composite container comprising a plastic bag of generally parallelepiped shape collapsible into flattened condition and a rigid knock-down type enclosure adapted to accommodate the plastic bag, said enclosure including a pallet-type base member and four side members having lower edges adapted to face the base member and upper edges, an opposed pair of said side members having notches in their upper edges, handle means secured to each of said pair of opposed side members and having a position in which the handle means is located substantially entirely within the effective confines of the corresponding side members, said effective confines being defined in part by the continuation of the upper edge over the notch, releasable assembly means for releasably fastening said pair of opposed side members to said base member, said releasable assembly means having a retracted position in which they are located within said effective confines of their corresponding side members, and releasable securing means for securing said adjacent side members to one another, whereby upon release of said securing means said enclosure can be disassembled and said side members and base members can be stacked in compact form with said releasable assembly means and said handle means in their retracted positions within the effective confines of their respective side members.
